摘要：This paper examines the existence of social welfare functions satisfying some reasonableaxioms of distributive equity and Pareto e.ciency in aggregating infinite utility streams. Ourmain results show that there exist social welfare functions that satisfy both the Pigou-Daltontransfer principle and weak dominance.a weak version of the Pareto principle., but thereexists no social welfare function that satisfies any of our distributive equity axioms and weakPareto principle simultaneously. Thus, we prove that no Paretian ranking can satisfy numericalrepresentability and any of distributive equity axioms in the setting of intertemporal socialchoice
